    Role of Copper


    • Copper is important in plant disease prevention - Plant diseases i.e. : net blotch, ergot and pig tailing
    • Copper affects lignin building qualities and is crucial in preventing lodging
    • Copper is important as a co-enzyme
    • Copper greatly affects kernel size and kernel weight
    • Copper and other micro deficiencies are enhanced by too much up-front NITROGEN early in spring
    • The window of opportunity to correct a Copper deficiency lasts until just before heading
